Bro, I already have ideas in head, but I'm terrible at expressing them in word or paper.

What I envision in my brain housing group is something similar to a Thompson, but with a reciprocating slide instead of internal bolt, pistol grip incorporating mag housing, mannlicher fore end (optional, but I think it looks sexy) in a take down format.

Sighting systems similar to many ARs. LER scope or red dot, flip up back ups. BUT... I like minimal to no rails. Personal preference.

Sorry it took awhile, we had a flooding issue we had to take care of (in the cold, POURING rain), then I got a call to go pick up my new (to me) shotgun.

Is this what you pictured? Its definitely different. I'd definitely buy one. It looks pretty cool.

As for the complete takedown or folding stock thing, I've never cared for the folding stocks. They've always just looks weird and uncomfortable to me. I like collapsible stocks, but I think a complete takedown option would be good for this kind of gun. It wouldn't be too hard to design it so that the barrel comes off like on the old takedown rifles.

Also, I'm not the best at GIMP (basically a free photoshop like program), but you get the idea. I think it would look better with a longer barrel though. (the stock could be made a little differently too)
